The term "turnpiker" is a somewhat antiquated word that originally referred to a person who collected fees at a turnpike. While this meaning is no longer relevant in modern times, there are several synonyms that can be used to describe someone who performs similar duties. A toll collector is a common term used to describe a person who collects fees on a road or bridge. Another possible synonym for turnpiker is gatekeeper, which can refer to a person who controls access to a particular area. Additionally, a traffic controller may also perform some of the same functions as a turnpiker, directing traffic and regulating the flow of vehicles.
